This is a very interesting book (with excellent illustrations) that introduces young children to various falcons living in the United States, some of their remarkable abilities and the story of how some scientists were successful in re-introducing the peregrine falcon in the Eastern United States after they nearly became extinct because of an insect spray called DDT which was overused earlier in the twentieth century. The story focuses on Scarlett, a peregrine falcon who was born in captivity, released, and discovered building a nest thirty-three stories up on the ledge of a skyscraper in Baltimore. This location made observation ideal and we learn that she managed to find a wild falcon for a mate and that their offspring have helped significantly in restoring the falcon population.
